Answer 1

Answer:

Total work done = clean 1 room

Time taken by

Nilo = 2 hours

Christian = 3 hours

Therefore, in 1 hour, cleaning done by

Nilo = 1/2th room

Christian = 1/3th room

So both of them together, clean (1/2 + 1/3) = 5/6th of the room in 1 hour.

So both of them will clean 1 room in

1 ÷ 5/6 = 1.2 hours.

a. 1/2

b. 1/3

c. 5/6

d. (1/2 + 1/3) = 5/6

e. G.C.D = 6

f. 1.2 hours
